CBO AOC SFP28 BlueOptics BO272703Q1M 1 m Passive Cable for SFP28 ports

Direct Attach Cable CBO AOC SFP28 BlueOptics BO272703Q1M 1 m Passive Cable for SFP28 ports is a one-meter passive assembly engineered for short-reach connections between compatible SFP28 network devices. The cable connects SFP28 ports directly, providing a fixed physical link that eliminates the need for separate transceivers. It is intended for use in dense rack environments where low latency, reliable signal integrity and reduced power consumption are priorities.

Advantages

This passive SFP28 cable offers a compact, low-cost connection method with low insertion loss and negligible added latency compared with active optical modules. By avoiding separate optical transceivers it reduces overall power draw and simplifies inventory and deployment. The one-meter length is optimized for rack-to-rack and switch-to-server cabling inside data center racks, delivering predictable electrical performance and consistent compatibility with SFP28 ports that support direct-attach passive cables.

Suitable for

• Short-reach interconnects between SFP28-equipped switches and servers
• Top-of-rack to middle-of-row or rack-to-rack connections within data centers
• High-density patching where fixed, low-latency links are required
• Environments where reduced power consumption and simplified cabling are needed

Key specifications

• Connector type: SFP28-compatible male connectors at both ends
• Length: 1 m passive assembly
• Data rate support: designed for 25 Gbps SFP28 links
• Cable type: passive electrical direct attach construction for short-reach links
• Form factor: compact SFP28 direct-attach cable for high-density ports
• Latency: minimal added latency typical of passive DAC designs

How to use

Install the cable by inserting each SFP28 connector into the corresponding SFP28 port on your network devices until the latch engages. Ensure devices are powered off or follow hot-swap procedures recommended by the device manufacturer before insertion or removal to avoid port damage. After physical connection, verify link status and speed through the devices' management interfaces and confirm that the ports accept passive direct-attach connections. Use one-meter length planning to avoid excess bending or strain on the cable and ports.

Usage recommendations

For reliable operation, use this passive SFP28 cable within short-reach scenarios inside racks or adjacent racks and avoid running it through long cable trays. Confirm device compatibility with passive DACs in your switch and server documentation and ensure ports are rated for 25 Gbps SFP28 passive connections. Avoid tight bends, excessive pulling force and exposure to liquids or extreme temperatures during installation and operation.
